Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/49406 ## Motivation Modernising the RN codebase to allow for modern Flow tooling to process it. ## This diff - Migrates Utilities/infoLog, Utilities/logError, Utilities/mapWithSeparator & Utilities/warnOnce to use the export syntax. - Updates deep-imports of these files to use `.default` - Updates the current iteration of API snapshots (intended). Changelog: [General][Breaking] - Deep imports to `Utilities/infoLog`, `Utilities/logError`, `Utilities/mapWithSeparator` or `Utilities/warnOnce` with `require` syntax need to be appended with '.default'.
